same thing happened to me

Hi @jaweii @catmasteryip , sorry for my delayed feedback.

I just released a new version of the BGSLibrary, now v3.1.0.
I tested it on Windows, Mac and Linux, both compiling the C++ library on OpenCV 3.4.7, 3.4.16 and 4.6.0.
I also tested its respective Python wrapper and GT user interface.

To install the Python Wrapper you have two ways to do it:

pip install pybgs

or

git clone --recursive https://github.com/andrewssobral/bgslibrary.git
cd bgslibrary
python setup.py build
python setup.py install

Everything is working for me, could you please check in your side if this new version fix your issues?
Thanks in advance,
Andrews
